when you send in a word to urban dictionary and regardless of how good it is, they reject it because they crave power, just like any media group on the planet. And similar to wikipedia, only accept words from a few contributors, probably because of bribes or sexual favors.

-I did, but i was urban dictionary censored. Dirty hoes.
